Visio Gantt chart- sub task roll up

[fillander]

Hi, I am new to this site.  Is it possible to roll up sub tasks in Visio like you can do in MS Project? I would like to be able to hide the subtasks when presenting to upper management.

ok, I guess there is no real solution to this problem. Is there another way to accomplish this using layers? I know you can add a layer that is not visible to 'hide' tasks however you get a lot of white space. Is there a way to hide this white space if I just wanted to show high level tasks and hide the sub-tasks?
